Title: Attitude controller for floating water vessel
Inventor: GAMOU KIYOSHI
IPC: B60V1/11
Filed: 1979-04-28
Abstract: PURPOSE: To perform the propulsion and the attitude control through the floating air, by forming a gate air chamber below the body while locating movable vanes in the air chamber, then exhausting rearwardly the air supplied under pressure from an upper front portion of the air chamber through lift fan.  
     CONSTITUTION: An air chamber A where the wall face 1 is placed vertically in the water while having gate-shaped cross-section is formed below the hull. Then movable vanes B1, B2 are fixed through shafts 2, 3 in the front and rear of the air chamber A. A lift fan 5 for supplying under pressure the air downwardly with respect to the air chamber A is located in a upper front portion of the air chamber A. Furthermore a rudder 6 is vertically provided at the rear of the wall face 1. Consequently the hull can be floated by applying the air pressure on the surface of water below the air chamber A by means of the lift fan 5. By regulating the angle of the movable vanes B1, B2 to the inflowing air the lifting force against the air flow or the water flow can be regulated to adjust the floating attitude, while the thrust is obtained by rearwardly gushing air flow.

Title: Induction-heated cooking apparatus
IPC: H05B6/12
Filed: 1992-03-12
Abstract: PURPOSE:To stop heating and inform a user of the abnormality of an apparatus when the opening/closing actions of an opening/closing device are inadequate by detecting the opening/closing states of the opening/closing device with electric signals such as the input voltage from an AC power source and the voltage across both ends of a switching element. CONSTITUTION:An opening/closing detecting circuit 13 detects the opening/ closing states of an opening/closing device 6 based on signals from an input power detecting circuit 8 and a switching element voltage detecting circuit 12 and feeds the output to an opening/closing control circuit 14. An oscillation prohibiting circuit 15 feeds the output to an oscillation control circuit 16 and prohibits the on/off oscillation of a switching element 9 when the state of the opening/closing device 6 is judged to be inadequate based on the output of the circuit 13. When heating coils 4, 5 are concurrently heated, the switching element voltage is lowered due to the relation between the input power from an AC power source 1 and the voltage across both ends of the switching element 9. When a threshold value is provided in the middle of both characteristics, whether a current is applied to the coil 5 or not can be judged.
